Point out the incorrect statement with respect to an electromagnetic wave in vacuum (or air) [2]. A. The color depends on the wavelength. B. The energy is transported with speed c in the direction of propagation. C. Both the electric field and the magnetic field exist in a plane perpendicular to the direction of propagation. D. The electric and the magnetic fields change in time, but do not change with position in space. E. The electric field vector and the magnetic field vector are always perpendicular to each…
